Marina Balmasheva, 37, already has a daughter with Vladimir Shavyrin, now 23, after first being married to his father Alexey Shavyrin.
During the COVID-19 lockdown, Marina opened up about her life with her stepson turned lover, sharing pictures of their first daughter, Olga.
The video posted by Marina shows the moment he met his daughter Olga for the first time.
She then went on to reveal the unconventional couple were expecting a second child who she has has now given birth to.
In Instagram updates announcing the birth, Marina shared a sweet image of the newborn laying in a cot, along with another image showing a hospital birth record announcing the baby’s arrival, captioned with the word ‘Hello’.
She calls her second husband ‘the most charming blue-eyes in the world’ but scolds him on social media for being ‘clumsy’ pushing their daughter’s pram, and failing to hold down a well paid job in Krasnodar region, close to Ukraine, where war is raging.
She makes clear that she supports him from her social media earnings rather than allow him to do a mundane office job.
After revealing her relationship with her former stepson, she said: ‘So many people tell me to use makeup – make lashes, and curl my pubic hair – because of my young husband.
‘But there is one thing – he fell in love with me with all my scars from plastic surgeries, cellulite, excessive skin and personality.
‘And I do not want to seem better than what I am.’
She also told how she had insisted on a prenup so that she keeps all her money and assets in case of divorce from her new husband.
Her ex Alexey bitterly told journalists: ‘She seduced my son. He had not had a girlfriend before her.
‘They were not shy to have sex while I was at home. I would have forgiven her cheating, if it wasn’t my son.
‘She was running to my son’s bed from our bedroom when I was sleeping.
‘After that she was coming back and lying in bed with me as if nothing had happened.’
Marina now says the previous marriage was ‘not living but pretending’.
She told her followers: ‘Did I have regrets that I destroyed the family? Both yes and no’
